Why is the abacus significant

The activity in the right hand helps them to coordinate and the left side of the brain and vice versa. This brings several benefits to the brain. Here are some of the key benefits of abacus learning. Thank you for sharing with us the key benefits of Abacus learning. Enjoyed reading it. Amazed to read about the benefits it has on the brain. Thanks for sharing the nice article!

Keep sharing this kind of valuable info through your blog. First of all ,thanks for sharing this article. As mentioned previously, the first abacus was designed to aid in certain forms of mathematics and computation, especially those that involved the addition of large sums of numbers.

Before the development of the abacus-or even the identification of specific numbers-individuals who were interested in adding large sums had to rely on the use of fingers, twigs, pebbles, and other similar objects. The abacus, which allowed merchants and other individuals to identify large sums without the use of these products, was a significant advancement in both the fields of science and business management.

According to most historians, the first abacus was developed in approximately BC. The oldest surviving abacus is traditionally referred to as the Salamis Tablet, and is believed to have been created in around BC.

The Salamis Tablet is around centimeters in length, 75 centimeters in width, and 4. Several vertical and horizontal lines divide the Salamis Tablet into unique sections, which may have been designed for specific functions. While the earliest abacuses were formed from wood, later abacuses-such as those created during the Roman Empire-were built primarily from stone or metal.

In addition, changes in the type of beads used on abacuses occurred around AD. Though originally positioned and manipulated in a vertical manner, abacus rods were soon changed to horizontal orientation.

Finally, further changes in both the structure and function of the abacus occurred in China and other Asian cultures in the mid th century. Over time, its popularity as a tool used in everyday computation decreased dramatically, likely due to improvements in the use and understanding of arithmetic and under mathematic concepts. Often, abacuses are compared to other computing tools, such as the counting board.

While these two products can both be used to compute numbers and perform other mathematical tasks, they are quite different in form. As mentioned previously, counting boards are often flat pieces of wood, stone, or metal, which feature painted or carved lines upon which stones, beads, or pebbles can be placed.

In contrast, abacuses consisted of rods held together in a sturdy frame. Beads or small pieces of glass could be moved across these rods, and used for basic computing and counting processes. It is important for individuals who are studying to abacus to remember that the device was not an early computer-but rather a tool that could allow the user to keep track of the place they were in their mental computations.

Despite its ancient origins, the abacus is still used by a number of individuals living in all parts of the world on a daily basis. As in years past, the abacus is commonly used as a rudimentary tool for the computation of mathematical equations. In addition, the use of abacuses has recently spread to the realm of childhood development. Many experts in the field of infant and youth development have come to understand the importance of hand-eye coordination and development, and the ways in which the abacus can be used to strengthen these skills.

Often, children and infants who struggle with gross motor skills are encouraged to build their coordination through the use of an abacus. In addition, some children-such as those with autism and other similar conditions-may also benefit from the use of tools that rely on repeated physical manipulation.

The abacus has been an important piece of equipment over the past several thousand years, but what does the future hold for this fascinating device? In addition to providing basic computing functions, modern abacuses allow users to perform multiplication and division, and determine the squared and cubed roots of certain numbers. Many experts agree that as humans begin to rely more and more on the use of technologically advanced devices, the science behind abacuses will continue to evolve.

This time-line above click to enlarge shows the evolution from the earliest counting board to the present day abacus.

The introduction of the Arabic numbering system in Western Europe stopped further development of counting boards.

Compare the quick rate of progress in last one-thousand years to the slow progress during the first one-thousand years of civilization. It is a slab of white marble measuring cm in length, 75cm in width and 4. In the center of the tablet are a set of 5 horizontal parallel lines divided equally by a perpendicular vertical line, capped with a semi-circle at the intersection of the bottom-most horizontal line and the vertical line.

Below these lines is a wide space with a horizontal crack dividing it. Below this crack is another group of eleven parallel lines, again divided into two sections by a line perpendicular to them but with the semi-circle at the top of the intersection; the third, sixth and ninth of these lines are marked with a cross where they intersect with the vertical line. Three sets of Greek symbols numbers from the acrophonic system are arranged along the left, right and bottom edges of the tablet.

During Greek and Roman times, counting boards, like the Roman hand-abacus , that survive are constructed from stone and metal as a point of reference, the Roman empire fell circa C. Over it is spread a cloth, bought in Easter term, with a special pattern, black, ruled with lines a foot, or a full span, apart. In the spaces between them are placed the counters, in their ranks.

The accountant sits in the middle of his side of the table, so that everybody can see him, and so that his hand can move freely at its work. In the lowest space on the right, he places the heap of the pence; in the second the shillings; in the third the pounds…As he reckons, he must put out the counters and state the numbers simultaneously, lest there should be a mistake in the number.

When the sum demanded of the sheriff has been set out in heaps of counters, the payments made into the Treasury or otherwise are similarly set out in heaps underneath. The lower line is simply subtracted from the upper. In the Middle Ages, wood became the primary material for manufacturing counting boards; the orientation of the beads also switched from vertical to horizontal.

In Western Europe, as arithmetic calculating using written numbers gained in popularity in the latter part of the Middle Ages, the use of counting boards began to diminish and eventually disappear by Arithmetic brought about the invention of logarithms by John Napier and logarithmic scales by Edmund Gunter.

In , William Oughtred used these two inventions together and invented the slide rule which lasted until modern times when the scientific calculator became popular in the early s. The abacus, called Suan-Pan in Chinese, as it appears today, was first chronicled circa C.

The device was made of wood with metal re-inforcements. Circa C. In Japanese, the abacus is called Soroban.

The design of the schoty is based on a pair of human hands each row has ten beads, corresponding to ten fingers. The abacus is operated by sliding the beads right-to-left. If you hold out both hands in front of you, palms facing out, you will see that your two thumbs are beside each other and two sets of 4 fingers spread out from there. Similarily, on the schoty , each row has two sets of 4 beads of the same colour on the outside, representing the two sets of 4 fingers and the two inner-most beads of the same colour representing the two thumbs.

The "home" position for the beads is on the right hand side.
